Doesnt play well in the news; it sounds like the killer is saying that she feels bad for killing one cyclst, severely injuring another, and it is their fault for being in her path. We have all been incensed at others for behaving in ways that cause near-misses, or maybe in disputes over whose "right-of-way" is the more important.
This is yellow journalism; heightens emotion, draws clicks, increases ad revenue. I cant comment on the Canadian legal system; it sounds like she's suing the estate of a dead person that likely contains zero, and two living boys that have little to even retain counsel and defend themselves. Slee Stak has it right, I think; its to distract and retaliate.
The lawsuits clog up the courts, but we respond to an interesting point; when a driver strikes another car, large animal, etc. in the road, most U.S. states consider the driver at least partly at fault for not being fully in contro; overdriving ones headlights and one's ability to react is NOT a defense when hitting a parked car, for example.
Cyclists are considered an annoying nuisance, and their rights to the road, even when legally protected, are still literally outweighed by automobiles' 'rights".
Stay safe, use all safety gear, get off the pavement if you must and carry a cell phone. A recent supreme court decison in the U.S. affirms the right of police to pull over any suspect driver, based on a 911 call. Imagine flashing lights a mile or two up the road.
